Patent number: 5266481Abstract: A post-fermentation degassing technique is provided which is directed for use in degassing foamed fermentation broths containing cultured microorganisms. Such a broth is charged while pressurized first through a heat exchanger to cool same, and then through a nozzle to form a spray suspension in a gaseous spray chamber located in a gravitationally upper part of a degassing vessel. The spray chamber is vented to the atmosphere. The spray suspension is coalesced to form a bulk liquid phase located in a gravitationally lower portion of the degassing vessel whereby the unpon surface of such bulk liquid phase forms the buttom surface of such spray chamber. The nozzle is so oriented that the spray suspension therefrom is downwardly directed towards the surface of the bulk liquid phase and the layer of foam characteristically formed thereon.Type: GrantFiled: May 31, 1990Date of Patent: November 30, 1993Assignee: Phillips Petroleum CompanyInventors: Eugene H. Wegner, Michael T. Seals, Lonnie C. Baugh, Bobby R. Harper

Patent number: 5177003Abstract: A process is disclosed for improving the flavor of protein products derived from microorganisms which comprises heat treating the microorganism and then drying same in the absence of a centrifugation. Optionally, the microorganism can be cultured in the presence of a flavor enhancing additive.Type: GrantFiled: November 19, 1990Date of Patent: January 5, 1993Assignee: Phillips Petroleum CompanyInventors: Lucas K. Shay, Dennis S. Banasiak, Trudy J. Fisher, Eugene H. Wegner

Patent number: 5149652Abstract: A post-fermentation degassing technique is provided for use in degassing foamed fermentation broths containing cultured microorganisms. Such a broth is charged while pressurized through a nozzle to form a spray suspension in a gaseous spray chamber located in a gravitationally upper part of a degassing vessel. The spray chamber is vented to the atmosphere. The spray suspension is coalesced to form a bulk liquid phase located in a gravitationally lower portion of the degassing vessel whereby the upper surface of such bulk liquid phase forms the bottom surface of such spray chamber. The nozzle is so oriented that the spray suspension it produces is downwardly directed towards the surface of the bulk liquid phase and the layer of foam characteristically foamed thereon. Additionally, a portion of the bulk liquid phase is recycled to the upper part of the vessel through a second nozzle to form a second spray suspension which is coalesced into the bulk liquid phase.Type: GrantFiled: May 29, 1990Date of Patent: September 22, 1992Assignee: Phillips Petroleum CompanyInventors: Michael T. Seals, Eugene H. Wegner

Patent number: 4970167Abstract: A post-fermentation degassing technique and apparatus are provided which is directed for use in degassing foamed fermentation broths containing cultured microorganisms. Such a broth is charged while pressurized first through a heat exchanger to cool same, and then through a nozzle means to form a spray suspension in a gaseous spray chamber located in a gravitationally upper part of a degassing vessel. The spray chamber is vented to the atmosphere. The spray suspension is coalesced to form a bulk liquid phase located in a gravitationally lower portion of the degassing vessel whereby the unpon surface of such bulk liquid phase forms the bottom surface of such spray chamber. The nozzle means is so oriented that the spray suspension therefrom is downwardly directed towards the surface of the bulk liquid phase and the layer of foam characteristically formed thereon.Type: GrantFiled: April 14, 1988Date of Patent: November 13, 1990Assignee: Phillips Petroleum CompanyInventors: Lonnie C. Baugh, Bobby R. Harper, Michael T. Seals, Eugene H. Wegner

Patent number: 4617274Abstract: Novel yeasts are disclosed including Pichia pastoris NRRL Y-11430, yeasts having the characteristics of Pichia pastoris NRRL Y-11430, mutants of Pichia pastoris NRRL Y-11430, and strains derived therefrom. Also disclosed are methods of culturing the strains, and biochemical conversions employing the strains.Type: GrantFiled: September 22, 1983Date of Patent: October 14, 1986Assignee: Phillips Petroleum CompanyInventor: Eugene H. Wegner
-
Patent number: 4601986Abstract: A nucleic acid-reduced substantially allergen-free single cell protein product is obtained by culturing a yeast, fungi or bacterium on an ultra-low sulfate medium, treating the produced cells with a base at a pH of about 9.5 with moderate heat, thereafter treating the base-treated cells with acid to a pH of about 4 with moderate heat, and treating the base-treated acid-treated cells with a relatively high temperature short time heat shock, followed by extrusion. Optionally, the extruded product is annealed.Type: GrantFiled: July 29, 1983Date of Patent: July 22, 1986Assignee: Phillips Petroleum CompanyInventors: Eugene H. Wegner, Lucas K. Shay

Patent number: 4439523Abstract: There is disclosed disposal of effluent from a low cell density fermentation process by using such effluent as at least a portion of the feed material to a high cell density fermentation process. A stream containing microbial cells from the high cell density fermentation process is subjected to direct drying.Type: GrantFiled: July 7, 1981Date of Patent: March 27, 1984Assignee: Phillips Petroleum CompanyInventors: Emil A. Malick, John W. Vanderveen, Donald O. Hitzman, Eugene H. Wegner

Patent number: 4439525Abstract: Mutant yeasts of the strain Pichia pastoris have been developed which contain relatively high levels of methionine. These high methionine content Pichia pastoris mutants grow on an oxygenated hydrocarbon such as methanol, to produce improved amino acid balance single-cell protein product eliminating or reducing the need to supplement single-cell protein with methionine when used as food supplements.Type: GrantFiled: September 9, 1981Date of Patent: March 27, 1984Assignee: Phillips Petroleum CompanyInventors: Lucas K.
